STOP-BOX.

SPECIFICATION forming part of Letters Patent No. 477,523, dated J une21, 1892.

Application filed October 7. 1891. Serial No. 408,051. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES G. ErrE, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Stop-Boxes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates particularly to certain details in theconstruction of stop-box covers and their locking mechanism; and itconsists in the construction, arrangement, and combination of theseveral parts of the device, substantially as will be hereinafterdescribed and claimed.

In the annexed drawings, illustrating myinvention, Figure l is aperspective view of my improved stop-cock box. Fig. 2 is a partialvertical section of the same with the cover in its locked position. Fig.3 isa similar view with the cover lifted and ready to be swungaroundinto the position shown in dotted lines. Fig. 4 is a top end orplan View of the upper end of the box with the cover removed. Fig. 5 isa top plan view of the box-cover. Fig. G isa bottom plan viewof thecover. Fig. 7 represents a cross-section of the cover on line a; of Fig.C and a side view of the upper end of the box.

Similar letters of reference designate corresponding parts throughoutall the different figures of the drawings.

A designates the outer and upper of the telescoping-sections of myservice or stop-cock box, said section having at its upper end thestop-box proper C provided With the cover D.

B indicates the inner or middle section of the stopbox. The outersection A is longitudinally-adjustable upon this inner or middlesection. Furthermore, it must be noted that the outer and upper sectionA is formed with a spiral thread or screw a., which is cast on or withthe box-section.

K designates the base of my improved serv ice or stop-cock box. Base Kis hollow and communicates with the tubular interior of the section B,and this base is provided at its lower edge with a broad Iiange orflanges B2, so that the base may have a solid or firm footing and restto stand on and may be held firmly down after the earth has been packedsolidly around it.

The inner or middle section B of my im proved stop-box is made ingeneral as a plain pipe, (see Fig. 2;) but near its upper end itsexternal surface is provided with a number of lugs or projections ofsuitable size and shape, east or otherwise formed thereon integral withthe substance of the inner tube. In the drawings, b Y) designate two ofthese lugs. These lugs are adapted to be engaged by the spirals a on theouter section A, as shown in Fig. 2, and therefore the lugs l) l) willbe so placed or situated relatively as to be at a proper distance apartto permit the spiral thread a to properly and successfully engage them.By simply taking hold of the upper and outer section A and giving it asimple turn either Way the height of the stopboX will be regulated andadjusted so that it may be kept level with the sidewalk or below it orin any other posit-ion, as may be desired. Furthermore, a sufficientfrost-lift is at all times provided for.

The cover D of the stop-box proper C is provided with a circular fianged, which fits down over the end of the upper box-section A and restswithin a suitable outer peripheral rabbet c, formed in said upper end.The flange d is inclined on its inside Wall at d. for about half itscircumference, the remaining half being straight on the inside, as atd2, or at right angles to the cover-top, (see Figs. 3, G,and 7;) alsothe rabbet. c has its upright side inclined inwardly from top to bottom,so that its upper edge will project outward farther than its lower edge,and thus provide an inclined ledge c', with which the flange CZ mayengage, and when they are so engaged the cover will be locked, becauseit cannot be lifted vertically.

The cover D is provided with a downwardlyextending pin F, which issecurely fastened to or made integral with the cover, which pin passesthrough a lug C, cast on the inside of the stop-box proper C, and saidpin being provided on its bottom end with a projection or pin f, whichis adapted to strike against the under side of the lug O after the coverhas been lifted. The lug C is provided with an elongated. slot e,through which the pin F ICO the top of the box.

passes, and which permits said pin to have afree inoveinent when thecover slides in locking and also when the cover is removed from Thus itwill be seen that the down wardly-projecting pin F enables the cover tohave a loose though permanent connection with the stop-box. Said pinpermits the cover to be lifted vertically for some distance, and thusremoved from the end of the box and turned around upon the pin, actingas a swivel, so as to open the end of the box; but the stop orprojection upon the lower end of the pin F prevents the said pin frombeing disengaged from the stop -box, and slot e, moreover, after thecover has been turned around into the position shown in dotted lines inFig. 3, permits said cover to be more coinpletely removed fromobstructing the opening in theboX by thrusting the pin F into the outerend of slot e.

The cover is formed upon its upper side with a depression or recess D',of suitable size and shape to allow the head of the bolt E to restneatly therein, which bolt-head is squared or otherwise shaped to permitthe application thereto of an operating-wrench for the purpose ofrotatingthe bolt. This bolt E passes down through the cover and issecured to a horizontal arin G, the lower end of the bolt being squaredor other shaped where it is connected to this arm, so thatthe'connectien is a rigid one and so that when the Wrench is applied tothe head of the bolt for the purpose of turning the same the said arm Gwill be turned in one direction or the otliei', as may be desired, andsaid arm is of a proper length to allow its outer end to strike againstthe inner side wall of the box, so that the result of shifting the armwill cause in this way the cover to be shifted sidewise and locked bythe engagement of the inclined edge of the iiange CZ of the cover withthe inclined edge of rabbet c in which ange d is seated.

Having thus described my invention, lwhat I claiin as new, and desire tosecure by Letters Patent, is-

The combination, with a stop-box having on the inside near the top edgea slotted lug and on the outside a peripheral rabbet whose upright wallis inclined inwardly from top to bottom to provide a locking-ledge, of acover having a downwardlyprojecting pin that passes through the slottedlug, and thereby loosely hinges the cover, and having also an encirclingange whose inner Wall is inclined for a part of its length and adaptedto engage the inclined ledge on the boX, and a bolt supported in aperforation in the cover, said bolt having its upper end suitablysquared for the application of a wrench thereto and carrying at itslower end a rigid arm, the outer end of which strikes against the insidewall of the box when the bolt is turned, and thus acts to shift thecover sidewise and lock the saine, substantially as described.
